2. The combination of a hanger comprising a pair of bearing portions, screw-plugs adjustable Within the respective bearing portions and having circumferential shoulders and terminal studs, one of the plugs being tubular and of L shape, a grease-cup applied to the latter, a tubular shaft provided with radial perforations and mounted between said shoulders upon said studs, and a cable-sheave mounted loosely upon said shaft, substan- I tions and mounted between said shoulders upon said studs, and a cable-sheave mounted loosely upon said shaft and having ahub, the ends of which are in contact with the inner ends of said bearing portions of the hanger, and wooden segments around said hub, extending outward to the groove of the sheave, substantially as hereinbefore specified.

4. In combination with a trench having a cross-bar with central lugs and a socket beneath the same, a hanger having a leg the lower end of which is fitted to said socket, and a hook fitted to the cross-bar between its lugs and having a pair of bearing portions at top, plugs fitted to the latter, a grease-cup carried by one of said plugs, a tubular shaft, and a loose cable-sheave, substantially as hereinbefore specified.
